	Create a constraint Order is the order of the constraint. The possible values for order are -1,0,1,2. Order i means constraints Gi Npt is the number of points associated with the constraint. TolDist is the maximum error to satisfy for G0 constraints TolAng is the maximum error to satisfy for G1 constraints TolCurv is the maximum error to satisfy for G2 constraints These errors can be replaced by laws of criterion. Raises ConstructionError if Order is not -1 , 0, 1, 2.

void	SetOrder (const Standard_Integer Order)
	Allows you to set the order of continuity required for the constraints: G0, G1, and G2, controlled respectively by G0Criterion G1Criterion and G2Criterion.

Standard_Integer	Order () const
	Returns the order of constraint, one of G0, G1 or G2.

void	SetG0Criterion (const Handle< Law_Function > &G0Crit)
	Allows you to set the G0 criterion. This is the law defining the greatest distance allowed between the constraint and the target surface for each point of the constraint. If this criterion is not set, TolDist, the distance tolerance from the constructor, is used.

void	SetG1Criterion (const Handle< Law_Function > &G1Crit)
	Allows you to set the G1 criterion. This is the law defining the greatest angle allowed between the constraint and the target surface. If this criterion is not set, TolAng, the angular tolerance from the constructor, is used. Raises ConstructionError if the curve is not on a surface.

void	SetG2Criterion (const Handle< Law_Function > &G2Crit)

Standard_Real	G0Criterion (const Standard_Real U) const
